Benchmarking a neutral-atom quantum computer

Abstract

In this study, we simulated the algorithmic performance of a small neutral atom quantum computer and compared its performance when operating with all-to-all versus nearest-neighbor connectivity. This comparison was made using a suite of algorithmic benchmarks developed by the Quantum Economic Development Consortium. Circuits were simulated with a noise model consistent with experimental data from [Nature604, 457 (2022)]. We find that all-to-all connectivity improves simulated circuit fidelity by $10\%$–$15\%$, compared to nearest-neighbor connectivity.
